Experimental investigation on dynamic stab resistance of high-performance multi-layer textile materials
Mulat Alubel Abtew, François Boussu, Irina Cristian, Bekinew Kitaw Dejene
Stab-resistant textiles play a critical role in personal protection, necessitating a deeper understanding of how structural and layering factors influence their performance. The current study experimentally examines the effects of textile structure, layering, and ply orientation on the stab resistance of multi-layer textiles. Three 3D warp interlock (3DWI) structures ({f1}, {f2}, {f3}) and a 2D woven fabric ({f4}), all made of high-performance p-aramid yarns, were engineered and manufactured.

Durable Textile Dyeing/Printing Using Natural Indigo Dyes and Leaves, and Mayan-Inspired Blue Indigo Pigments. Colorants, 4(1).
Behary, N., & Volle, N.
Indigo leaves from various plant species are sources of dyes/pigments, not fully exploited for making sustainable textiles. Blue indigo vat dye extracted from indigo leaves yields high wash color fastness but fades slowly with light, and is not easily used for direct printing. Indigo leaves can be used to produce textiles of various color shades, while light-resistant Mayan-inspired hybrid pigments have not yet been used for textile coloring.

Reliability modeling of tensile properties in recycled carbon fibers: A comparative fit of statistical distributions pre- and post-textile processing
Jean Ivars, Kim Phuc Tran, Ahmad Rashed Labanieh, Damien Soulat
Due to their extensive use in the aerospace, automotive, wind energy, and sports industries, the recycling of carbon fiber composites has become increasingly important. Characterization of the tensile properties of these recycled fibers is essential, using single fiber tensile tests that provide data on tensile strength, elongation at break, and tensile modulus. This study compares four statistical distributions—2-parameter Weibull, 3-parameter Weibull, Normal, and Lognormal—to fit tensile data from two batches of recycled carbon fibers: one after recycling, and the same type of fiber after a further carding process.
